Global warming in the past 30 years had serious effects on agricultural land and its crop suitability in the Iclod Commune, whose agricultural land evaluation database still uses old temperature and precipitation averages. Using WorldClim monthly temperature and precipitation distribution maps, History+ simulated archive database and SRTM’s slope steepness and orientation, raster calculations were performed in GIS for a fast update of temperature and precipitation distribution maps which were then used to update the OSPA’s agricultural land qualitative assessment database. The results show that the last 30 years hot and dry tendencies substantially modify Iclod Commune’s land evaluation database, suggesting that new crops are more suitable than the old ones in face of the current accelerated climate change tendencies.

In this paper will be covered the previous works on the preservation of the environment of city urban areas, which can mobilize resources of urban agriculture. The need for creating favorable environment for human life in the last decade become a key issue, ie. how to repair the problems of environmental pollution from the products of human activity, and how to change the an awareness of such a lifestyle. The reduction of green areas, with a disproportionate increase in the number transport vehicles and pollution from agriculture and other economic activities, inducing specific "urban" environment. Its characteristics condition the temperature rise of 2-6 degrees of cities, increased concentration of pollutants harmful to human health, as well as the disappearance of plant species typical for the locality. In order to increase the surface area covered with vegetation, and in accordance with horticultural principles, characteristics can be used for special purpose lawn. The lawn is an integral part of bio-gases, which fully reflects, by combining vegetables, flowers and ornamental trees. It is therefore important to know the possibilities for utilization of grass species, as well as respect for the calendar works entering the lawn and measure their recovery in order to get the desired results. In this way will be possible to integrate the point of production from the standpoint of environmental protection. With respect to the concept of urban and peri-urban agriculture, with food production in urban conditions, together with landscaping of public and private property there will be favorable conditions for sustainable development of rural and urban areas.

For passive and low energy buildings, such an external envelope, which can provide a sufficient thermal insulation function with the smallest overall wall thickness., is thermally and financially the most advantageous. Concrete can be a suitable building material. At present, non-reinforced porous concretes, light autoclaved concretes (sand and ash concretes) are used as good insulating materials. New thermal insulating concretes designed by us can be classified into this category. At the same time it is possible to prove by their previously non-tabulated heat penetration parameters that these materials are of relatively higher quality. Use of these materials brings the same effect of desired thermal insulation by only a comparatively small reduction in the concrete wall thickness. As a result, it is possible not only to achieve savings of the indoor living area, but also to declare a more favourable parameter of the building energy intensity, which is a highly reputable parameter. The solved issues are important in agriculture, especially in terms of dimensioning the purpose-built buildings, such as residential buildings, livestock buildings, silos and various buildings designed for storage. With regard to the assessment of the entire life cycle of buildings and the durability of concrete, the choice of this material is favourable both from the viewpoints of power consumption, environmental impacts and economy.

Global warming is a factor that has widened over the last period of time, so monitoring ground temperature is needed to take measures to prevent this phenomenon. In the hope of preserving life on earth and bring balance in our life, as we use to have it, it is up to our civic duty to share the essentials of the scientific research done, for the doctoral thesis and came with some ideas and suggestion, to help our community to reach our goal. The objective of the study will describe a methodology used for estimating the terrestrial surface temperature by means of the geographic information systems technology, using the two Landsat thermal bands, acquired by the Thermal Infrared Sensor (TIRS) installed on the Landsat 8 satellite platform. A case study on the administrative area of Cristuru Secuiesc, located in the South-West part of Harghita County, will be approached in the paper. The primary data base consists of thermal bands (band 10 and band 11) and multispectral bands (2, 3, 4, 5) from the Landsat 8 mission, taken with OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors. To carry out the study, the NDVI index will be calculated using the multispectral bands, while the thermal bands will be converted to several physical quantities in order to obtain the desired result. The paper describes the process of collecting data and processing it, to obtain valuable information on the surface temperature experienced by a computer, without the need for field measurements.

In seismic areas, present and future generations may suffer because of vulnerable built heritage. Security of life in large and densely populated urban settlements involving protection against multiple hazards/threats of the system depends of exposed elements such as buildings or landscape elements and utility networks, social and economic functions, and population. In rural settlements risks can be different with a higher contribution of natural environmental factors: slopes, areas with high level of groundwate etc. This article will present: - Factors depending of seismic risk, in conjunction with sociology, individual and collective psychology, risk perception and social behavior of human community, government and emergency management; - Seismic education programs in the past 20 years, knowledge and the actions needed to behave rationally and effectively, to deal with rumors, panic, to prevent disasters and survive, strengthen and restore buildings and places and life after seismic events with negative effects; - A new concept and applications offered through the Centre for information, education and training of the population; The new approaches take into account the need to use reliable earthquake engineering researchers of URBAN-INCERC, INCERC Bucharest Branch, for training, to identify the gaps in present public information and to cover all age and professional categories of population and public servants, to teach them practical approaches to protect and cope with disaster impact.

Most widely applied technologies wastewater treatment biological technologies are based on the selection of microbial communities dominated by bacteria (activated sludge).Wastewater treatment through Moving Bed Biofilm Bioreactors (MBBRs) has been widely used during the last years. The wastewater treatment with moving bio media consists in adding biofilm carriers (small cylindrical/ round/ plate shaped polyethylene/polypropylene/ polyurethane foam carrier elements) in aerated or anaerobic basins to support biofilm growth. The paper explored the functionalization of MBBRs (polyethylene support) structures in a Biotec FE 007 fermentor, with Cerioporus squamosus strain (a basidiomycete bracket fungus). Scanning Electron Microscopy and optical microscopy analysis were carried out pre and post microbial functionalization on the MBBRs in order to assess the colonization of the MBBRs structures and internalization of microbial biomass. The functionalized MBBRs will be further used in experiments of removal of recalcitrant compounds from cellulosic wastewaters.

The paper is intended to present some aspects regarding the safety evaluation methods by determining those defining characteristics of a structural system (behaviour in time through dynamic characteristics evolution). This assessment should first be initiated in the case of buildings with essential functions and which could pose a major threat to public safety in case of collapse or serious damage. Determining, using intelligent wireless sensor networks, used within of a real-time data transmissions system, of some accelerograph data obtained from earthquakes with significant magnitude, will lead to an image of the spatial distribution of peak ground acceleration (PGA). Obtaining additional data over time will highlight some conclusions about acceleration values and directivity of seismic waves in the territory. On the other hand, the determination of the dynamic characteristics of structural systems by non-invasive and non-destructive instrumental measurements, under normal micro-seismic agitation, offers the possibility of obtaining important data in the structural safety assessment process after a major earthquake. Correlation of structural dynamic information, determined in situ and by analytical approaches, is a necessary step in the continuous process of risk exposure in an area with disaster potential. Data about a few study cases are presented.

Due to the time evolution of the design provisions, there are buildings that were designed decades ago, using less stringent provisions. Thus, when the earthquake is produced, there are many cases where the buildings are badly damaged. Structural engineering is closely related to parameters such as acceleration, velocity, displacements, and spectral composition, therefore, with the widespread use of strong motions apparatus, in the ‘70s they started seismic instrumentation with help of seismic stations located in the buildings, dams and bridges. According to the modern approach of the post-seismic investigation the damage building assessment should be clearly foreseen and properly planned in order to obtain dynamic parameters for the analysis. The objectives of the paper are to present both a new concept for building performances assessment and a modern solution for building strengthening. All the aforementioned ideas are illustrated through a study case. The dynamic parameter evolution of 3D model of reinforced concrete at natural scale it will be analysed. In case of masonry panels inserted in reinforced concrete frames a modern and efficient solution is panel strengthened with Carbon Fibers as fabrics and plates. Therefore, the researches on the strengthening solution effectiveness of masonry walls are presented. Experiments on a large scale of modular elements of masonry buildings, tested and strengthened with CF were carried out in Research and Testing Laboratory on Materials, Components and Structures for Buildings - INCERC at universal press 4MN, submitted them to compression on diagonal direction. The results were demonstrated that the application of CF on the masonry panels is efficient, but to optimize costs it is necessary to review the size and disposal of plates used.

The surface and subsurface drainage systems developed in the Moldova River watershed in the County of Suceava have been designed to be used on drainage sectors, and, in order to enhance excessive water capture and discharge, several complementary works have been planned from time to time, namely: land levelling, shaping, deep loosening etc. Due to the extension of the private ownership of the land with drainage systems starting with 1991 and due to the carrying out of soil works on individual plots of land, the land was shaped in the bedding with ridges and furrows, of variable widths, level differences and transverse slopes. Land shaping that does not match the routing of the plastic drain lines and of the drainage network allows the water to stagnate in the furrows and extend the excessive humidity period. The use of the developed areas on drainage sectors facilitates the levelling of small depressions and supports the even removal of excessive water. As maintenance works have not been performed from time to time, this has gradually led to the erosion of slopes and to the slitting of the canal network and of the discharge holes in the drains, which caused excessive humidity to reoccur.
